AI Technical Summary

Technical Problem

The existing traffic light system cannot automatically adjust the green light duration in real time according to changes in vehicle and pedestrian traffic. This results in the green light running empty when there are no vehicles or pedestrians crossing in a certain direction, increasing waiting time and reducing traffic efficiency, especially at intersections with low traffic volume.

Method used

Infrared sensors are used to detect vehicles and pedestrians in all directions in real time. The analysis program determines whether to extend the green light or change the light earlier, avoiding empty runs during green lights and ensuring smooth passage for vehicles and pedestrians.

Benefits of technology

It effectively avoids the phenomenon of empty runs under green lights, improves the efficiency of intersection traffic, reduces waiting time for vehicles and pedestrians, ensures the fairness of right-of-way at intersections, and is low in cost, making it suitable for intersections with low traffic volume.

Abstract

The application discloses a method and system for loading intelligent intervention and adjusting a traffic light on the basis of an existing traffic light, relates to the field of traffic light control, and discloses a method and device for real-time intervention and adjusting a traffic light, which greatly improves traffic efficiency. The method mainly comprises the following steps: an infrared induction probe is used to sense the conditions of vehicles and pedestrians in specific areas in each direction in real time; and through analysis, it is determined in real time whether to trigger intervention and adjust the traffic light or to extend the green light time of a certain direction for a single time on the basis of the existing traffic light time setting operation, so that the situation that a certain direction is in green light but there is no vehicle and pedestrian in the certain direction (green light "empty running") and the situation that vehicles and pedestrians in other directions stop and wait for red light are completely avoided, unnecessary waiting time is completely avoided, and the traffic efficiency of the intersection is greatly improved. The application is suitable for intersections with small traffic flow, i.e. intersections with green light "empty running". For intersections without green light "empty running", the application has no practical significance.
